Sayl

Sayl by Herman Miller

The Sayl chair is said to be "fewer parts, less material, and still everything a good chair should be". One of its features is a suspension back that provides sacral support. This support is important to help your spine into a healthy and natural posture. It comes with two back options; an upholstered back and a breathable 3D intelligent suspension back.
